Distributed Energy Systems NorthWind 100 - 100kW Wind Turbine
| The NW100 occupies a vital place in the micro wind market. With many manufacturers now withdrawing from this size of turbine or imposing minimum and prohibitive order quantities (such as 10-15), the NW100 is available in single units and within short time frames. Supplied on a 25m monopole tower (or taller) the NW100 is potentially suitable for the built environment in which turbines on 18-20m hub heights are being typically being recommended. The NW100 is also supported with noise data conducted to IEC standards. The manufacturers of the NW100 Northern Power Systems have been designing and engineering wind turbines and power electronics for variable speed direct drive systems since the 1970s. They are a founding member of the American Wind Energy Association (AWEA) and are regularly asked to comment on turbine performance, design and engineering. NW100 wind turbines are located throughout the world, including the South Pole, the Sahara Desert and the National Renewable Energy Laboratory's National Wind Test Site at Golden, Colorado. Their turbines in Antarctica have successfully operated for almost 20 years in winds up to 88.5 m/s (198 mph) and temperatures as low as -80º C (-112º F). |  |
